Hey PK,
The problem is, it's not entirely clear whether the issue is yours or the platform's. If you'd like, you can post to the public issue tracker, but that would also require more information and code to reproduce, or at the very least an app id and affected timeframe, so that it can be looked-into and determined to be an issue rather than your own issue. This doesn't come from any kind of lack of trust directed towards you or any user, it's just that issue reports on any software project will need to have some minimal guarantee that the issue is actually existing in the code which the project you report to is able to fix, rather than your own project / code / configuration.
The kind of information I think might be relevant:
1. the cron task configuration data
2. the code of the handler
3. description of steps you've taken to ensure possible alternate causes aren't at fault (is your log-level set correctly in the logs viewer?)
You can certainly check using google whether others have had issues like yours using a combination of keywords, and while it's true that making a post to a forum to ask others might be useful, the way you phrased your question wasn't indicating that, and seems to look for an individual solution, which isn't the purpose of the forum.
I wish you the best in finding a solution by posting to either stackoverflow or the public issue tracker. I'll leave this thread open to replies, of course, if anybody happens to see this thread and also have input, although be advised that specific resolution of this issue should occur on stackoverflow or the public issue tracker, if investigation and work on the issue is needed, rather than just +1 comments from other users.
Best wishes,
Nick
